A high white blood cell count (WBC), also known as leukocytosis, can be caused by a variety of infections, including bacterial, viral, fungal, or parasitic infections.
The body increases its white blood cell production in response to these infections to fight off the invading pathogens.
Here are some examples of infections that can cause a high WBC:
- Bacterial infections: Pneumonia, urinary tract infections (UTIs), skin infections, and sepsis.
- Viral infections: Influenza, mononucleosis, and COVID-19.
- Fungal infections: Candidiasis (yeast infection), aspergillosis, and histoplasmosis.
- Parasitic infections: Malaria, toxoplasmosis, and giardiasis.
It's important to note that a high WBC can also be caused by other factors, such as inflammation, stress, certain medications, and some types of cancer.
If you are experiencing a high WBC, it is important to consult with a healthcare professional to determine the underlying cause and receive appropriate treatment.
